Bowers & Wilkins PI5 review: Sophisticated style, big bass sound

"Slick and stylish, the PI5 offer an alternative to white plastic earbuds.". It took Bowers & Wilkins (B&W) longer than expected to launch its first true wireless earbuds, but they're finally here: The $400 flagship PI7 and the step-down PI5, which cost $250. The slick-looking earbuds hit the market at a pivotal time when most brands are already working on their second-, third-, or even fourth-generation products, having had years to learn and make improvements. Can B&W jump in with a first-gen product with a top-tier price and give the incumbents like Sony, Bose, Jabra, and JBL a run for their money?
